File Encryption CLI

Description

File Encryption is command-line tool used to encrypt and decrypt files using AES and RSA encryption algorithms. It is written in Python and uses the PyCryptoDome library.

Requirements

• Python 3.6 or above
• PyCryptoDome library

Installation

1. Install pycryptodome library

pip install pycryptodome

2. Clone the repository

git clone https://github.com/ezhil56x/file-encryption-cli.git

3. Go to file-encryption-cli directory

cd file-encryption-cli

4. Take a look at the help menu to see the usage of the tool

python file_encrypt.py --help

python file_decrypt.py --help

Usage

AES Encryption

Encrypting a File

To encrypt a file, using AES encryption, use the following command

python file_encrypt.py --file <file> --algorithm AES --key <text>

Decrypting a File

To decrypt a file, using AES encryption, use the following command

python file_decrypt.py --file <file> --algorithm AES --key <text>

RSA Encryption

For RSA encryption, you need to generate public and private keys. You can use the key_generator.py script to generate the keys. And the keys will be stored in public.pem and private.pem files. You should move these files to the same directory as the file_encrypt.py and file_decrypt.py scripts.

Encrypting a File

To encrypt a file, using RSA encryption, use the following command

python file_encrypt.py --file <file> --algorithm RSA --key public.pem

Decrypting a File

To decrypt a file, using RSA encryption, use the following command

python file_decrypt.py --file <file> --algorithm RSA --key private.pem

Generating public and private keys

To generate public and private keys, go to RSA folder and run the following command

python key_generator.py
